Description
Data Records
The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 40,721 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
Versions
The table below shows only published versions of the resource that are publicly accessible.

Sampling Methods
Volunteers checked nests in nestboxes and a small number of wild nests. They recorded lay date, clutch size and brood size. These data were gathered into a physical dataset by the Plantenziektekundige Dienst.

Method step description:
- Source files were scanned and digitized using the pre-trained Transkribus model 'The Text Titan I' for text recognition, the 'Universal Lines' model for layout recognition, and a machine learning model trained on 80 manually transcribed pages for table recognition. The raw text output was cleaned with manual review and automation using Python with pandas and regex libraries.
- Datafication included standardizing area and observer names. All areas were manually geographically coded using historical Esri maps of the Netherlands. Species taxonomy was mapped to the vernacular names using the taxize package in R.
- Quality control included reviewing suspicious values (e.g. outliers, improbable and impossible values) against the source material. The data was furhter validated against the original reports from the Plantenziektekundige Dienst (ongoing).
